It doesn't have a basement, and I can't say how descent the crawl space is, so I really don't know how accessible that area is. 

What about the plumber that stops a flooding leak on a Sunday morning or the HVAC tech that fixes a furnace under a crawl space in the middle of a freezing night?

There is another way to see the listing prices history if I can't see it on those webs?

Online Auction Sites - Realauction.com, LLCYes you're right, but it's not the only one, there are other platforms depending of the state and the tax lien type (e.g. redeemable has a specific platform), some county has his own system, finally, the main difficulty is to be updated on all upcoming auctions and retrieve the lists to do the research.There are no other platforms for the counties appearing on the Realauction web site. 

As you may know, Podio is web-based which allows custom apps which can be automated by talking to your other web-based applications via Zapier.

.#1 mistake is not using the right advertising websites correctly.So, ask your agent for a list of websites they are advertising your properties on.May also help if you post JUST the address here - we should be able to do a web search and find it - or there's an obvious advertising problem!

Does anyone have any recommendations, or even better any spreadsheets, excel or web-based, they use to keep track of all construction expenses for Flip/BRRRR properties? 

Be more discreet and search the web first.The goal is to help you get better answers and less pitches.

I have a proof of concept web page and can provide a personal story and touch.

That’s my advice anyway, I’m relatively young and take a huge swing at two out of state properties that ended up working out but I wish I would have crawled before I walked if that makes sense.
